mechanism is to share and reuse same address space among different network segments.

This mechanism mitigates the problem of the shortage of IPv4 address temporally;

meanwhile it adds the burden of address translation process for network device and

application. Since the address space of IPv6 has increased greatly, address translation

becomes unnecessary, thus the problems and system cost caused by NAT deployment

are solved naturally.

Support extensively deployed Routing Protocol. IPv6 has kept and extended the

supports for existing Internal Gateway Protocols (IGP for short), and Exterior Gateway

Protocols (EGP for short). For example, IPv6 Routing Protocol such as RIPng, OSPFv3,

IS-ISv6 and MBGP4+, etc.

Multicast addresses increased and the support for multicast has enhanced. By

dealing with IPv4 broadcast functions such as Router Discovery and Router Query, IPv6

multicast has completely replaced IPv4 broadcast in the sense of function. Multicast not

only saves network bandwidth, but enhances network efficiency as well.

3.2.2

IP Configuration

Layer 3 interface can be configured as IPv4 interface, IPv6 interface.

3.2.2.1 IPv4 Address Configuration

IPv4 address configuration task list:

1. Configure the IPv4 address of three-layer interface

1． Configure the IPv4 address of three-layer interface

3.2.2.2 IPv6 Address Configuration

The configuration Task List of IPv6 is as follows:

1. IPv6 basic configuration

(1) Configure interface IPv6 address

Command

Explanation

VLAN Interface Configuration Mode

ip address <ip-address> <mask>

[secondary]

no ip address [<ip-address> <mask>]

Configure IP address of VLAN

interface; the no ip address [<ip-

address> <mask>] command

cancels IP address of VLAN

interface.
